Definitions
- the invention is concerned with the use of derivatives of a specific diastereomer of prostaglandin F 2alpha , viz. 11 epi, for the treatment of glaucoma or ocular hypertension.
- the invention furthermore also relates to ophthalmological compositions containing an active amount of these prostaglandin derivatives.
- Glaucoma is an ocular disorder characterized by elevated intraocular pressure, excavation of the optic nerve head and gradual loss of the vision field.
- An abnormally high intraocular pressure will have a generally detrimental effect on the eye; and there are clear indications that this is probably the main factor causing degenerative changes of the retina in glaucoma patients.
- the pathophysiological mechanism underlying open-angle glaucoma is still unknown. If not treated successfully the disease will usually proceed to blindness sooner or later, its course towards that stage being characterized by a slow but progressive loss of vision.
- This uveoscleral path has been described by e.g. Bill (1975).
- the pressure gradient along this path is very insignificant as compared to the gradient in the first mentioned case over the interior wall of Schlemm's canal and adjacent tissue.
- the flow-limiting step along the uveoscleral path is believed to reside in the flow from the anterior chamber into the suprachoroidal space.
- IOP P e + (F t - F u ) x R
- P e and R have the same meanings as above
- F t represents the total outflow: of aqueous humor
- F u represents that portion thereof which goes via the uveoscleral path.
- the IOP will normally be within the range of from 12 to 22 mm Hg. At higher values, e.g. exceeding 22 mm Hg, there is a risk that the eye may be affected.
- the so-called low-tension glaucoma lesions will occur at intraocular pressure levels which are generally regarded as physiological. Possibly this may be due to an increased pressure sensitivity of the eye of such an individual.
- the opposite type of phenomenon is known, i.e. some individuals may have in abnormally high intraocular pressure without any noticeable distinct defects in their vision field or optic nerve head. Such conditions are usually named "ocular hypertension".
- Glaucoma treatments may be given by means of drugs, laser or surgery.
- the purpose is to achieve a reduction of either the flow (F) or the resistance (R), which will result in a lower IOP according to formula (1) above; or alternatively, the purpose may be to increase the flow via the uveoscleral path - which too will be a means of lowering the pressure as can be seen from formula (2).
- Cholinergic agonists like for instance pilocarpine reduce the intraocular pressure mainly by increasing the outflow through Schlemm's canal.
- prostaglandins and derivatives thereof are described in for example US 4599353 and EP 87103714.9.
- prostaglandins and derivatives as suitable as drugs for treating glaucoma or ocular hypertension, a limiting factor is their property of causing superficial irritation and vasodilatation in the conjunctiva. It is probable moreover that prostaglandins have an irritant effect on the sensory nerves of the cornea. Thus local side effects will arise in the eye already when the amounts of prostaglandin administered are quite small - that is, already when the doses are lower than those that would be desirable for achieving maximum pressure reduction. It has thus been found for instance that for this reason. It is clinically impossible to use PGF2 alpha -1-isopropyl ester in the amount that would give maximum: pressure reduction.
- Prostaglandins being naturally occurring autacoids are very potent pharmacologically any affect both sensory nerves and smooth muscle of the blood vessels. Since the effects caused by administrations of PGF 2alpha and its esters to the eye comprise in addition to pressure reduction also irritation and hyperemia (increased blood flow) the doses currently practicable in clinical tests are necessarily very low.
- the irritation experienced when PGF 2alpha or its esters are applied consists mainly in a feeling of grittiness or of having a foreign body in one's eye, this beinG usually. accompanied by increased lacrimation.
- the 11 epi PGF 2alpha -1-isopropyl ester which as far as we know has not been described heretofore will give rise to hyperemia in the conjunctiva to about the same extent as the PGF 2alpha -1-isopropyl ester, but this will not involve any hazard or inconvenience as long as irritation problems are absent.
- the present invention thus relates to 1-alkyl or 1-alkylaryl esters of 11 epi PGF 2alpha to be used for treating glaucoma or ocular hypertension.
- the alkyl chain of the 1-alkyl esters comprises 1-10, preferably 1-7, and especially 1-5 carbon atoms.
- the 1-alkylaryl esters have an aryl group monosubstituted by a lower alkyl chain. This lower alkyl chain has 1-5 carbon atoms.
- the 11 epi PGF 2alpha -1-isopropyl ester is used.
- compositions for the treatment of glaucoma or ocular hypertension said compositions containing an effective intraocular pressure reducing amount of at least one 11 epi PGF 2alpha -1-ester defined as above, in an ophthalmoiogically compatible vehicle.
- effective amount here means that the composition contains about 0.1-10 ⁇ g, especially 1-10 ⁇ g of the active substance.
- the ophthalmologically compatible vehicle which may be employed for preparing compositions of this invention.
- the vehicle furthermore may contain ophthalmolegically compatible preservatives such as e.g. benzalkonium chloride, surfactants like e.g. Tween® 80, liposomes or polymers, for example methyl cellulose, polyvinyl alcohol, polyvinyl pyrrolidone and hyaluronic acid; these may be used for the purpose of increasing the viscosity.
- ophthalmolegically compatible preservatives such as e.g. benzalkonium chloride, surfactants like e.g. Tween® 80, liposomes or polymers, for example methyl cellulose, polyvinyl alcohol, polyvinyl pyrrolidone and hyaluronic acid; these may be used for the purpose of increasing the viscosity.
- a method for treating glaucoma or ocular hypertension consists in contacting a composition as aforesaid with the eye in order to reduce eye pressure and to maintain said pressure on a reduced level.
- the composition contains 0.1-10 ⁇ g, especially 1-10 ⁇ g, of the active substance i.e. the 11 epi PGF 2alpha ester; the treatment may advantageously be carried out in that one drop of the composition, corresponding to about 30 ⁇ l, is administered about 1 to 4 times to the patient's eye.
- PGF 2alpha -1-isopropyl ester or 11 epi PGF 2alpha -1-isopropyl ester produced according to Example 1 was mixed with an eye drop solution containing 0.5 % Tween 80 as a micelle-forming substance plus 0.01 % benzalkonium chloride as a preservative to 50 ⁇ g/ml concentration. Healthy volunteers received in one of their eyes one drop (30 ⁇ l) containing 1.5 ⁇ g of either PGF 2alpha -1-isopropyl ester or 11 epi PGF 2alpha -1-isopropyl ester, and in the other eye one drop of the vehicle without any added prostaglandin compound, this other eye being the contralateral control eye.
- Eye pressures were measured 2, 4, 6 and 8 hours after administration of 11 epi PGF 2alpha ,-1-isopropyl ester, and 4 and 8 hours after administration of PFG2 alpha -1-isopropyl ester. With prostaglandin eye drops the maximum pressure reducing effect in the eye is expected to be achieved 6-8 hours after administration of the preparation.
- Eye pressure was measured by means of applanation tonometry, either with Godmann's applanation tonometer or with a pneumatonometer (Digilab Mode -30RT), after anesthesia of the cornea with oxybuprocaine drops or with a mixture of oxybuprocaine and fluorescein. Results could be read only after measurements were complete.
- This pressure reduction may appear to be a small one, but it is a well-known fact that normotensive individuals will generally show fairly little reaction in response to pressure reducing drugs. This is true also of e.g. pilocarpine and timolol.
